Fig. 6, is e section on f Patenten Apr. @3men e.l deteile description of the preiernerifI form of embodiment of my inventiomthe numeral 1 designates the ey and 2 the tire rim of an automobile wheel- Provided on. the inner periphery of the tire rim Q .'ere preferebiy four luge 3 edaptedto eesiiyen# ter four vrespective inwerdiy tapering slot ai nrrengeri te 'receive them in. the outer en I nuinr edge of the feiiy bend of the felyl.

Referring to Figs.

Theee'iienges 6 en ii 7 are adapted to mount iangee, Senti Sie" speetively, formed on the outer peripiierg of the elly band, the tepel' of the letten-f enges running in e direction opposite tof that of the ienges 6 end 7,' whereby, wia the vtire rim is forced inwardlyfri 'jt wedges 5, the flanges 6 and? wiii tight y gege the ienges und 9 te ineke e 'okee between the tire rimend feiiyfhen From the above it will heeheerveei thm the greater the inward. movementof the tir., rim 2 is, the tighteritwill ding to the feiy bend, 1. In other worde, as the tire rimis turned to the right, the more'irmly will, it' wedge itself upon the feiy hen 1. Ton maintain it in its wedged Jposition, the iel iowing construction is provided. Referring to Figs. 1, 12 end M.' there is 'ggivoteily semired to the side ef thergeliy l y menne of e bolt l0 and; nut l, g1, ioeiring lever: 12. The

latter is adapted to be swung into the positionshown in Figs. 1 and 12, to bring its i lower threaded` end of the counter boreA 16.

'position upon the felly band it is turned to",

(See Fig. 1li).` When the tire rim 2 is in a position to engage the plunger *13.v in the .direction of its,l length, thereby resiliently maintaining the tire rim 2 in its wedged positionl on the fellyband after having been forced tdt-he right. The force with .which it is heldin such position maybe varied by turning the adjusting screw 18 in the cylindrical lcounter bore 16.

In order to hold the locking lever 12 firmly in the positionin which it is shown in Figs. 1 and 12, o'r 'its locking position, the

followingdevice is provided. Referring to Figs. 1411 and '12, n there is preferably screwed to the felly 1, a socket 19 having a" countersunk portion 20. extending well into the felly. In this counter-sunk portion 20L the lower end of a plunger 21 is movable against the pressure of a coil spring'22, the latter being adapted to force the outer end of said plunger across the path of circumferential movement of the locking lever- 12,

l' the lugs 3 to bewithdrawn from the slots 4 in the felly band, which operation dispenses;

to prevent its rearward movement when in engagement with the plunger 13. By pressing inwardly upon the plunger 211, said locking leverw12 may be readily' withdrawnfrom engagement with theouter end of the plunger 13 to permit'the tire rim 2 to be taken ofi". After the lever 12 is withdrawn from '45 engagement with the plunger v13, it is only necessary,to remove the tire rim, to turn it to 'the left a'sufficient distance to permit with the laborious one ofv removing numerous nutsl as in the case o f the presentdemountable rims.

To apply the tire rim rto the felly band, it

is kfirst necessary to force the vaive stem 23y through a longitudinal slot 24 provided in l'the felly band vof the felly 1,'as shown in Figs. 9 and19, ,whereupon said tire rim may 4 `be' turned to the right as 'beforeoxplainem with the valve stem 23 free to travel through the slot 211l during said turning operation. It 1s unnecessary to turn any nuts to wedge lthe tire rim on' the 'felly band, for, as the former is turned to the right, it is forced inzlardly on 'the fellyy band of the felly 1 by wedge s.5, and the greater its inward tween the flanges 6 and 7, and 8 and 9 here-- tofore described. To maintain the tire rim,

in its running position on the felly band, the

locking lever 12 is then brought into engagement with the plunger 13, afterwhiclr the plunger 21 is snapped across its path by the Acoil spring 22 to hold itin its locking position.

I do not wish to be limited to thedetails of construction and arrangement herein shown. and described, and. any changes or modifications may be made therein within the scope of thesubjoinedv claims.

Having described my invention, .l claim: y 1. In a device of the type specied, the combination with a felly band provided with slots in its periphery, of a tire rim provided with projecting elements on its inner periphery adapted to enter said slots which termi nate near the middle of the felly band,

wedge shaped members on the felly band at the side ofsaid slots, adapted to be engaged by said tire rim elements toforce the tire inwardly Ias it is turned circumferentially, means on said tire rim and felly band adapted to wedge the former firmly on the latter as said tire rimr is forced inwardly, a plunger on said tire rim, a felly to which said felly band is fixed, and a member pivotally secured to said flelly,"adapted toengage said plunger in the'direction of its length, to holdsaid tire rim in its wedged position on said felly band.
